Test FAQ 1
It may be perhaps surprising to know but a large portion of the River Thames is actually tidal, and hence subject to tides. Of the Thames’ 346km (215 mi) total length, 160km (99 mi) is in fact tidal, that’s close to half of the length. This section, which is known as the Tideway, stretches all the way from the sea until stopping at the first lock on the river in Teddington. The Tideway includes Thames Estuary, the Thames Gateway and the Pool of London.
